Nickel Clad Copper Conductors Engineering Inquiry
Nickel clad copper combines a nickel outer layer with a copper core for project-specific evaluation where surface behavior, weldability, corrosion exposure and conductivity must be balanced.
Final temperature, joining and environmental limits depend on product geometry, nickel ratio, service atmosphere and assembly design. NCC is not equivalent to nickel-plated copper; product suitability must be confirmed through agreed inspection and application tests.

What is Raytron NCC?
Raytron NCC (Nickel Clad Copper) is a bimetallic conductor combining a nickel outer layer with a copper core, available as round wire, flat wire and other forms by project review.
- Conductivity
- Conductivity depends on the nickel layer ratio and construction. Confirm measured values per product and lot in your RFQ.
- Service temperature
- Long-term service temperature limits for nickel-clad copper are application- and construction-dependent. Request validation data for your specific use case.
- Suitability
- NCC is not equivalent to nickel-plated copper. Product suitability must be confirmed through agreed inspection and application tests.
- About ASTM B355
- ASTM B355 covers nickel-coated soft or annealed round copper wire. It is not presented as a universal standard for metallurgically clad NCC.
Manufacturing Process
This product is manufactured using Clad & Weld process with metallurgical bonding. It is NOT electroplated.
Metallurgical bonding creates a permanent metallurgical connection, ensuring stable reliability compared to electroplating. This enables excellent weldability, designed to resist peeling during bending, and stable performance under thermal cycling conditions.
NCC vs Bare Copper — What to Evaluate
Where bare copper alone does not meet surface or corrosion requirements, NCC is evaluated as a candidate conductor. Each dimension below must be validated for the specific application.

Joining method
Welding, crimping or pressure-contact processes must be validated for the nickel layer configuration and conductor geometry.
-
Atmosphere & medium
Atmosphere, corrosion medium and exposure duration define the boundary conditions; provide full duty parameters.
💡 Temperature, joining and corrosion limits depend on geometry, nickel ratio and service environment — include duty parameters in your inquiry
Temperature Profile Review
Service temperature limits depend on product geometry, nickel ratio, service atmosphere and assembly design. Provide your temperature profile and exposure duration for review; no fixed temperature rating is published before the technical review is complete.
Corrosion Exposure Review
Conclusions on salt spray, ammonia, acid/alkali and other corrosive environments require an agreed test basis (medium, concentration, temperature, duration). Submit your actual service environment for review.
Clad vs Plated — Design Difference
The cladding process creates a metallurgical bond designed to resist delamination under specified forming and bending conditions. NCC is not equivalent to nickel-plated copper; final performance must be validated for the target application.
Application Scenarios
Challenging the harshest industrial and scientific environments
Li-Battery / Storage Tab Connectors
Engineering evaluation scenario: where tab connections need nickel-side welding compatibility together with a conductive copper core, NCC can be evaluated as a candidate conductor. Electrolyte exposure and welding parameters must be validated per project.

Frequently Asked Questions
Technical Details & Selection Guide
What applications is Nickel Clad Copper evaluated for?
NCC is evaluated for projects where conductivity, surface behavior at elevated temperature and corrosion exposure must be balanced. Suitability must be confirmed through agreed inspection and application tests. Medical, aerospace and other high-risk applications follow a controlled engineering-inquiry process and are not marketed as normal applications.
What is the maximum operating temperature of NCC?
Long-term service temperature limits for nickel-clad copper are application- and construction-dependent (product geometry, nickel ratio, service atmosphere and assembly design). Until the technical review is complete, we do not publish a fixed operating temperature; request validation data for your specific use case.
Can the nickel layer configuration be customized?
Nickel ratio and layer configuration are set per project. State the required nickel-ratio basis (weight, cross-sectional area or thickness) and conductor geometry in your RFQ so the specification review can proceed.
How does Nickel Clad Copper differ from Nickel Plated Copper?
NCC uses a cladding process in which the nickel layer is metallurgically bonded to the copper core, designed to resist delamination under specified forming, bending and thermal-cycle conditions. NCC is not equivalent to nickel-plated copper; final performance must be validated for the target application.
